In Hongdan, a hotel must provide a certain number of high-end conveniences to be rated 5 stars. These can include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused standard of service. You'll enjoy things like nightly turn-down services, in-room massages and concierge services. Some may also offer extra touches such as a welcome gift.
